Fri, 02 Mar 2018 21:21:12 +0000http://www.shockwave.me.uk/?p=178#comment-109554Many, many, many thanks. Seriously, I can’t thank you enough. I was ready to pull my hair out over DHCP being obstructed by my firewall. I was looking everywhere for instructions on which files to specifically create a firewall exception for, how to do so and where to locate these files.

For some reason (Apple not trusting their users I guess?) it’s impossible to search for items located in hidden folders in the search panel within the exception-adding tool in System Preferences. The workaround is to simply navigate to the /usr/sbin folder using the Finder’s “Go to Folder” functionality, then drag-and-drop the required files into the firewall exceptions list.

In my case, I had to reboot my machine (2010 13″ MBP, Snow Leopard) for the exceptions to become effective.

How did I get myself into this situation? My system clock got reset to Jan 1st, 2001. (I’m too embarassed to admit that I let my battery run completely flat). Tried to connect to Wi-Fi and/or Ethernet before setting the clock, and voilà, everything went pear-shaped.

The one take-away is: Set the system clock before connecting to any Wi-Fi and/or Ethernet!

Sat, 27 Feb 2010 10:57:17 +0000http://www.shockwave.me.uk/?p=46#comment-252As good practice you should also change the default location that computer accounts appear from the computer container to a locked down ou.
You need to make sure your domain is in Windows 2003 mode or higher, and then issue the command

redircmp ou=lockedcomputers,DC=homer,dc=co, dc=uk
Note When Redircmp.exe is run to redirect the CN=Computers container to an organizational unit that is specified by an administrator, the CN=Computers container will no longer be a protected object. This means that the Computers container can now be moved, deleted, or renamed. If you use ADSIEDIT to view attributes on the CN=Computers container, you will see that the systemflags attribute was changed from -1946157056 to 0. This is by design.

Sat, 27 Feb 2010 10:26:42 +0000http://www.shockwave.me.uk/?p=145#comment-251You can get something very similar to the above happing if the computer account password for the DC gets out of sync. You can connect to the DC from another workstation but when the server tries to connect to itself you get the error described. To resync you will need to use netdom
Another alternative is to perform a restore of the DC?

Firstly I think it’s great that HP are trawling the web for feedback on their products. I would be very interested to talk to you regarding HP Openview and the extensive issues that we have experienced with the product.

Whilst I recognise that I hadn’t sent any staff on Openview training, we really hadn’t progressed that far… Being a large HP customer we had very quickly decided that Openview was an obvious choice to monitor and report on our 500+ sites and 400ish servers. To expedite this, I contacted HP directly who put me in contact with a ‘partner’ for the pre-sales, purchase and implementation of the products.

Starting with NNM and progressing to include OVO and OVPI we suffered with an implementation that spanned (from memory) around a year… This partner were simply unable to make the product perform, we were stunned given that we knew the product was held up to be the de-facto industry standard and all of the good stuff we were promised in the pre-sales.

As issues progressed, we actually suffered an outage caused by the OVO agent which grew to consume all memory on multiple servers including Domain Controllers, this strangled Active Directory and prevented replication (which was only picked up by Spotlight on AD).

The above example as well as other issues led us to remove the againts as a matter of priority and speak directly to HP once again. The action taken was to review the install and produce a report which was pretty damning. HP promised to resolve this for us but as yet have been unable to do so.

To date, I have replaced the server monitoring with Microsoft SCOM but have no method of monitoring the network infrastructure across the country due to the partner still not being able to resolve the issues… We are now two years on and still at square one.

I would welcome a discussion with someone at HP to actually resolve this as I feel I’m getting nowhere and am now seeking a refund for OVO at least.

Rob.

I cannot really comment on the mismatch between your requirements for reporting and the type of reports that OV Performance Insight is delivering ‘out of the box’. Patently there is mismatch of expectations which I suspect may be related to some misunderstanding or miscommunication during the sales process. I cannot really add any further detail there other than to state that we have many thousands of OVPI users who are definitely happy that it delivers the value that they expected.

You do not state which “OVO” version you have – OMW or OMU (we dropped the “OVO” acronym a couple of years ago) . IN either case there is out of the box integration with NNM. NNM is actually an integral part of an OMU install up until version 9.0 (which was just released). And for OMW we provide an NNM adapter as part of the OMW install. Integration exists, is pretty good (and we’re working to provide even more value) and is free of charge.

I’m concerned when you state that you have not sent anyone to the training classes for these products. These products are all advanced, industrial strength (industry leading) technologies. They have huge amounts of functionality in order to enable them to address the requirements of the broadest and most varied customer base. This does imply that some training is needed in order to appropriately configure the products to meet your specific needs. IMO you’re being a little unfair in venting about the technology when you’ve not trained your personnel to make best use of the products.
And I say this as someone who HAS implemented NNM and “OVO” (OMU and OMW) for a number of large customers in the past (I’ve only been a marketeer for a couple of years).

With regards to “OpenView” not being ‘open’. I have to disagree.
Yes you’ve found the ITRC forums but you’re missing a number of other resources which are available.
First I’d suggest that you join and start participating with Vivit – the independent HP Software User Group. http://www.vivit-worldwide.org There is a UK chapter lead by Tim Foxon.
Another resource you might want to look at for “OVO” is http://www.ovinternals.com This is a free (non-HP owned) library of utilities to enhance OVO installations. I know that many of our customers learn about this when they go to HP training classes.
